Hello to all users.!
I have audison LRX 1.400 and at beginning when i want to connect power supply(12v+- rem),amplifier start for 2 seconds and stop during DC current protection on speakers output.I removed output fet's but without any good results.After further investigations that auxiliary supply was found out of order.I need some diagram for this aux power supply.!!See pictures.

Problem was found about for this amplifier.some regulator for 15v supply was in short circuit and did some damage to one pcs op-amp.i replaced everything and i tested with 2 output transistor and with my scope Tektronics tds i have clean sinus wave.i hope this week to mount all transistors(new) and to bias them.
